    2. By means of the PB 25, the sharpening element 23 is moved to the saw chain 7. The springs 30 evenly press the base with the sharpening device 13 to the moving chain 7. Adjusting and fusing the sharpening device 13 using the PB 25 and the latch 29 ensure the precision of the saw chain 7. Placing a sharpener 13 in K ensures the safety of the sharpening process of the saw, 8C. f-ly, 15 ill.
    It has 9 branches, and containing cutting teeth 10, which after blunting are subject to sharpening.
    Casing 1 consists of two pivotally connected removable sections II and 12, made of synthetic material. Inside the casing from the side of the closed end is installed grinding
    0 device 13. It is performed as follows. On the inner side, to the side wall 14 of section 12, is attached a C-shaped base 15, preferably made; from syntetic material.
    On the base 15, three guide pads 16 are made. At each of the end sections 17 of the base 15, one guide block 16 is arranged. A third guide bar 16 is located approximately in the central part of the base 15. Base guide bars 15 are placed in holes 18, made mutually pa5 papelnO in the longitudinal direction of the casing 1 in the side wall 14. The base 15 is attached with screws 19 to the side wall 14. Screws 19 are screwed into the thread of the bobber 16,
    0 and the head 20 of each screw 19 and the washer 21 are recessed in the recess 22. On the concave end surface of the base 15, facing the saw chain 7, there is fixed an arcuate sharpening element 23.
    In order to fine-tune the base 15 and the sharpening element 23 located on it, on the end wall 24 of the casing 1 an adjusting

    screw 25. The latter has a fungus 26, which is located outside the casing 1 in front of the end wall 24. The thread 27 of the adjusting screw 25 is located coaxially with the longitudinal axis of the casing 1 and is located in the thread 28 of the base 15.
    To prevent the adjusting screw 25 from being inadvertently moving and locking it from rotating, a latch 29 is installed between the fungus 26 and the end wall 24,. The base 15 is under the influence of springs 30 directed to the saw chain 7. Parallel helical springs 30 are located on either side of the adjusting screw 25 and are located in the hollow recesses 31 of the base I5, with one end adjacent to the end wall 24 of the casing 1.
    The arcuate sharpening element 23, located on the concave end surface of the C-shaped moving base 15, is U-shaped in cross section and consists of a web 32 and two obliquely diverging lateral shoulders 33 at an angle of the PO from its ends on the end sections 17 of the base 15. The fork end 34 of the metal support 35 of the sharpening element 23 is secured with a screw 36 on the end portion 17 of the base 15. The other forked end 34 of the metal support 35 is clamped under the hook 37 of the clamping pin 38. flax pivotable about an axis 39 and biased by means of compression spring 40. To provide quick replacement grinding element 23 to the next, the clamping lever 38 is provided with a terminal 41 projecting beyond the casing 1 at its upper longitudinal side 42 of the split.
    On the back side of the metal bearing 35 of the sharpening element there are two protrusions 43 fixed in recesses 44 located on the concave end surface of the movable base 15. The grinding tool 23 has a fiber pad 45 and an abrasive layer 46. A fibro pad 45 on which the abrasive layer 46 is located , is attached by an adhesive substance to the inner surface of the metal support 35. The grinding element 23 in cross section is designed in such a way that on the abrasive layer 46 in the places of the main section mating

    the bands 32 and the side arms 33 are rounded 47, the radius of which is 0.8 mm.
    On the side wall 48 of section 11
    the casing 1 has an arcuate viewing hole 49 for observing the sharpening element 23. In addition, on the side wall 48 of the section 11, a position indicator 50 is installed, by means of which the determination is made. dividing the corresponding position of the sharpening device 13. The positioning indicator 50 of the sharpening device 13 has an indicator window 51 formed by the sidewall 48. At the upper edge of the indicator window 5I there is a scale 52. In the indicator window 51 there is a protrusion 53 visible on the movable base 15 .
    To ensure that the center plane of the tire 2 coincides with the center plane of the casing 1, two adjustment screws 54 are mounted in the side wall 14 of section 12, respectively. On the opposite side wall 48 of section I1, respectively, between the adjustment screws 54, a countersor 55 is installed, abutting the other side of the tire 2. To prevent the adjustment screws 54 from turning, lock nuts or other locking elements may be used.
    Sections II and 12 of the casing I on the side of the bottom wall 56 are interconnected by two hinges 57. On the opposite detachable longitudinal upper wall 42 of the casing 1 there are two locks 58. Each lock 58 is made in the form of a slide mounted on the detachable longitudinal wall 42 of the casing 1, which provided with protrusions 59 and 60 to form a guide, 61 in the form of a dovetail. In this case, the lock 58 is made by overlapping the guide 61 and the connector of the upper longitudinal wall 42.
    The side wall 14 of the casing 1 is provided with locking cams 62 located in the zone of its longitudinal central axis, passing through the holes in the tire 2 and fixed in the holes 63, B1 filled in the side wall 48 of the section 1 1.
    The casing 1 can be provided with a pivot about an axis, perpendicular to the central longitudinal plane of the casing, and located on the side

    CTCHKG 14 near the split longitudinal wall 42 T-shaped bushing 64. In this case, the side. The wall 48 is made with the corresponding slot 65.
    The casing 1 can be provided with two locks 66 with locks 66 located on its longitudinal central axis. Each key 1 screw lock 66 has a rotating handle 67 located on the side wall 4 of section 12. The threaded portion 68 of the lock 66 is located in the holes of the side wall 14 and Iiny 2 and fixed in the threaded sleeve 69 installed in the side wall 48.
    The work is carried out as follows.
    When the saw 3 is in operation, the casing is removed from the bus 2 by means of the locking connector. Sharping the chain 7 by means of the grinding chain 7 the casing 1 with the sharpening device 13 is put on the tire 2. By means of the adjusting screw 25, the sharpening element 23 is gradually moved relative to the saw blade chain 7 up to the norm, while in the viewing hole 49 there is no spark from grinding.
    When adjusting the sharpening device 13 by means of three guides of the bobbie 16, in the parallel longitudinal holes 18, the moving base 15 is moved. Both vuttovye springs 30 evenly press the movable base 15 to the moving chain 7. Adjustment with the adjusting screw 25 and the presence of the lock 29 in it ensures the TO4HOCTJ5 processing of the saw chain 7. Thanks to the clamping 38, you can easily and quickly replace the grinding tool item 23,
    The placement of the sharpening device 13 in the housing 1 provides simplicity and reliability of service i which increases the safety of the sharpening process.
